Description of drawings
Fig. 1 is an overall structure schematic diagram of the present utility model.
The specific embodiment
The utility model is described in further detail below in conjunction with concrete drawings and Examples.
As shown in the figure: fixedly install cylinder sleeve 13 at upper cylinder cover 17 end faces, sealing slidely connects piston sheet 15 in the last cylinder sleeve 13, connect piston rod 14 on the piston sheet 15, described piston rod 14 bottom sliding plugs are in the upper end of intermediate 7, upper cylinder cover 17 or on offer the air inlet 16 that is positioned at above the piston sheet 15 on the cylinder sleeve 13, sliding plug has depression bar 6 in the installing hole hypomere of intermediate 7, described depression bar 6 upper surfaces offer blind hole downwards and form shoe cream room 19, on intermediate 7, offer the fuel feed hole 8 that is communicated with shoe cream room 19, the bottom intermittence of piston rod 14 stretches into shoe cream room 19 and compresses the hydraulic fluid of shoe cream room 19, intermediate 7 belows are fixed with down cylinder cap 9, the upper end of following cylinder cap 9 is fixed with spring base 3, between spring base 3 or following cylinder cap 9 and intermediate 7, be fixed with the following cylinder sleeve 5 that they are connected as a single entity, the bottom sliding plug of depression bar 6 is stretched out downwards in the intermediate 7 of following cylinder cap 9 and from the lower surface of following cylinder cap 9, the bottom of depression bar 6 is fixed with installs screw rod 1, outside depression bar 6, be socketed with back-moving spring 11, be provided with outwardly directed spacing back-up ring 20 at the stage casing of depression bar 6 sidewall, on the described back-moving spring 11, the bottom is restrained between spacing back-up ring 20 and the spring base 3.
Described installation screw rod 1 is fixed on the depression bar 6 by screw rod pressing plate 2, and upwards offers one section blind hole formation cutter installing hole 21 at installation screw rod 1 bottom face.On intermediate 7, offer the venthole 12 of the interior gas pressure that is used for venting piston sheet 15 and last cylinder sleeve 13 formation cavitys.On spring base 3, offer and regulate valve opening 10.Offer center air blowing air admission hole 4 on the spring base 3, the inner end of described center air blowing air admission hole 4 extends to the lateral wall that screw rod 1 is installed.In the installing hole of intermediate 7, be fixed with the dust ring 18 that is socketed in outside the piston rod 14.
